_III. Is one who possesses a given trait in high degree a better or worse judge of that trait than is an individual in whom the trait is less conspicuous?_ On the basis of the combined judgments of the group we have secured a final position for each individual, which indicates her most probable standing in the various traits. Since each individual judged all the others of the group, we can, by correlating[12] the judgments of each individual with the combined judgments of the group, secure a coefficient of correlation which will indicate the "judicial capacity" of the given individual. This figure will be a measure of the correctness or representative character of her judgments of her friends. If the figure is low, it will mean that her own judgments do not agree closely with the combined or true judgments. If the figure is high it will indicate that there is close correspondence, and that the individual's judgments of her friends agree closely with the combined judgment. Having secured these measures of judicial capacity, and having also measures of the degree to which each individual possesses the various traits, we may by correlating these two measures determine whether or not any relation exists between possession of the trait and ability to judge others with respect to that trait. In the same way we may determine the relation between possession of the trait and ability to judge oneself in that trait. The table on page 160 gives these coefficients of correlation in the case of all the traits.
In the cases of neatness, intelligence, humor, refinement and sociability the coefficients are all positive and fairly high. Thus in the case of humor the coefficients of .59 and .87 indicate that that individual whom others consider humorous tends to be the most correct or representative of the group in her judgments of the humor of herself and of others. The coefficients of .49 and .59 in the case of intelligence indicate that that individual who impresses others as being intelligent is a good judge of intelligence both in herself and in others. The same is to be said of neatness, refinement and sociability. In the case of beauty the coefficients, although positive, are very low and hence not very reliable. They seem to indicate that in this case there is no relation of any sort between the possession of the trait and the ability to judge it.
